• Tongs or spatula
• Measuring spoons and cups
• Knife and cutting board

Prep and timing

Total time: about 20 minutes. Active time: about 10 minutes.

Step-by-step instructions

Follow these rewritten, clear directions in the same order as the original source, with amounts and ingredient names preserved from the ingredient list.

1. Prepare the salmon. Pat your salmon dry with paper towels. If you are using four pieces, lay them skin-side down (if skin-on) or presentation-side down on a clean surface. If you are using a 1 pound slab, lay it flat. Sprinkle the 2 tablespoons lemon pepper seasoning evenly over all pieces, pressing gently so the seasoning adheres. Let the seasoned salmon rest while you preheat the air fryer.
2. Preheat the air fryer. Set your air fryer to the recommended cooking temperature for salmon (typically 400°F / 200°C). Allow it to preheat for 2–3 minutes so the basket reaches temperature; this helps create a crisp exterior.
3. Toast the sliced almonds. While the air fryer preheats, place a small skillet over medium heat. Add the 1/4 cup sliced almonds to the dry skillet and toast, stirring or shaking the pan frequently, until the almonds are golden and fragrant, about 2–3 minutes. Watch them closely so they don’t burn. Remove the toasted almonds from the skillet and set aside.
4. Air fry the salmon. Lightly oil the air fryer basket or spray with a neutral cooking spray if desired to prevent sticking. Place the seasoned salmon in a single layer in the basket, skin-side down if applicable. Cook at 400°F (200°C) for 8–10 minutes for individual pieces, or 10–12 minutes for a 1 pound slab. The exact time depends on the thickness of your fillets; salmon is done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C) if you use a thermometer.
5. Make the almondine butter. While the salmon cooks, return the skillet to low heat and add the 1 tablespoon butter. Once melted, stir in the toasted sliced almonds, coating them in the butter. Remove the skillet from heat and stir in the 1 tablespoon lemon juice to bring brightness to the nutty butter. If you like, fold in the optional 2 tablespoons chopped green onions now for a mild oniony finish.
6. Finish and serve. When the salmon is cooked through, transfer it carefully from the air fryer to serving plates. Spoon the almondine butter and toasted almonds over each piece of salmon, making sure each portion gets an even scatter of almonds and a drizzle of the lemon-butter sauce. Garnish with any remaining chopped green onions if you used them. Serve immediately.

Serving suggestions

This salmon pairs beautifully with simple sides that soak up the lemon-butter sauce:

• Steamed or roasted asparagus
• Garlic mashed potatoes or creamy polenta
• Mixed greens with a light vinaigrette
• Butter or lemon rice

Tips and tricks for perfect results

• If your salmon has skin and you prefer it crisp, place it skin-side down in the air fryer. For super-crisp skin, pat the skin very dry before seasoning.
• Do not overcrowd the air fryer basket. If using four pieces of salmon, leave a little space between them or cook in two batches for the best air circulation and even cooking.
• Watch the almonds closely when toasting and when cooking in butter; they can go from golden to burnt very quickly.
• Adjust lemon pepper seasoning to taste. If you like a stronger lemon note, add an extra quarter teaspoon of lemon pepper, or a squeeze more lemon juice when finishing.
• Allow the salmon to rest for a minute after cooking; this helps the juices redistribute for a moist final bite.

Variations and swaps

Want to change things up? Try these simple variations while keeping the core technique intact.

• Maple-mustard glaze: Whisk 1 tablespoon Dijon mustard with 1 tablespoon maple syrup and brush on during the last 2 minutes of air frying for a sweet-savory finish.
• Pecan or walnut almondine: Swap the sliced almonds for chopped pecans or walnuts for a different nuttiness and texture.
• Herb-forward: Mix chopped parsley or dill into the almondine butter for an herbaceous lift.
• Spicy citrus: Add a pinch of crushed red pepper or cayenne to the lemon butter for a kick.

Make-ahead and storage

If you want to prep ahead, you can season the salmon up to a day in advance and keep it refrigerated, covered. Toasted almonds and the almondine sauce are best made just before serving, but toasted almonds will keep in an airtight container at room temperature for a few days. Leftover cooked salmon will keep in the refrigerator for up to 2 days; reheat gently in the air fryer at a lower temperature (300°F / 150°C) for 3–4 minutes to avoid overcooking.

Why the air fryer is ideal

The air fryer creates a high-heat environment that crisps the surface of the salmon while keeping the interior tender. It shortens cook time and delivers a texture that’s reminiscent of pan-searing but with less hands-on time and fewer dishes to wash. Because the almonds toast quickly on the stovetop, you can multi-task and prepare the finishing sauce while the fish cooks.

Notes on ingredient choices

• Salmon: Choose fresh, firm fillets for best texture. Thicker pieces will need the longer end of the cooking time range.
• Lemon pepper seasoning: This packet typically contains lemon zest and cracked pepper; it’s the primary flavor driver here, so choose a blend you enjoy.
• Sliced almonds: Pre-sliced almonds toast more quickly and give a clean, elegant look to the finished dish.
• Butter: Adds a rich, silky mouthfeel to the almondine sauce and helps carry the lemon flavor.
• Lemon juice: Brightens the finish and balances the richness of the butter and almonds.

Common questions

Can I use frozen salmon? Yes. Thaw frozen salmon completely in the refrigerator before seasoning and air frying. Cooking from frozen will require more time and may cause uneven results.

How do I know when the salmon is done? The safest indicator is an internal temperature of 145°F (63°C). Otherwise, the salmon should flake easily with a fork and still appear moist inside—avoid overcooking to keep it tender.

Can I skip the butter? You can substitute a neutral oil, but the butter adds richness and helps the almondine sauce feel like a proper finish. If you prefer oil, use a mild-flavored oil and add a little extra lemon juice for brightness.
